Specification of Letters Patent.

Patented May 14, 1907.

Application filed March 30,1906. Serial No. 808,968.

To all who/'11 1115 'ntmy concern:

Be it known that I, CHRISTOPHER FIELD- ING, a citizen of the United States, residing at South Bethlehem, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in Hinges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in. the art to which it appertains to make and use the same.

My invention relates to new and useful im provements in hinges and more particularly to that class adapted to be used in connection with window blinds and doors of like nature and my object is to provide a hinge of this class which will securely lock said shutter or the like in its open position.

A further object'is to provide means for holding said shutter in its proper plane while being opened or closed.

A still further object is to provide means for holding the locking mechanism inoperative while the shutter or the like is being opened or closed.

Other objects and advantages will be hereinafter referred to in the specification and pointed out in the claims.

In the accompanying drawings, which are made a part of this application, I have shown the preferred form of my invention.

In said drawingsFigure 1 is' an elevation of my improved hinge showing the leaves thereof open. Fig. 2 is a top plan view of the hinge open. Fig. 3 is a vertical, central, sectional view as seen from the dotted line 33 Fig. 1, and, Figs. 4 and 5 are perspective views of the two parts of the hinge separated.

Referring to the figures by numerals of reference, 1 and 2 are the leaves of my improved hinge, said leaves being of the usual or well known form, the leaf 1 being provided at one edge with a head 3, said head being oblong in cross section and extending substantially half the length of the leaf and is provided with a depending pivot pin 4, said pin being preferably placed to one side of the center of the oblong head 8. The leaf 2 is also provided with a head 5 said head being similarly constructed to the head 3 but at the opposite end of the leaf from the head upon the other leaf. The head 5 is provided with a socket 6 into which is adapted to take the pivot pin 4 and by which means the two leaves are operatively connected together. The head 5 is provided with an outwardly projecting ledge 7 at its upper end, said ledge being adapted to enter a way 8 in the leaf 1 when the shutter is being opened or closed. The opposite side of the head' IB from that containing the pivot pin 4 is provided with an elongated bore 9, said bore having a shoulder 10 near its upper end as best shown in Fig. 3 of the drawings. A locking pin 11 having a reduced portion 12 is inserted into the bore 9, said reduced end having a spring 13 disposed therearound and between the shoulder 10 and the locking pin proper 11 whereby downward pressure will be exerted-upon said locking pin at all times. The extreme upper end of the reduced portion 12 has secured thereon a handle or knob 14 by which means the locking pin 11 is elevated. When the shutter or the like is open, the locking pin 11 takes into a bore 15 in the head 5, said bore being disposed on the opposite side of said head from that. occupied by the socket 6.

In operation, when the shutter or the like is opened the spring 13 will direct the locking pin 11 into the bore 15, thereby locking said shutter in its open position and retaining the same therein until it is desired to close said shutter when, by grasping the handle 14 and elevating the pin 11 out of engagement with the bore 15, the shutter may be closed. As soon as the leaf 1 carrying the shutter has been moved sufficiently to bring the locking pin 1 1 out ofengagement with the bore 15, said pin may be released whereupon the lower end thereof engages the upper surface of the head 5 and ledge 7 and rests thereon as long as the shutter remains closed. As the shutter is being closed, the ledge 7 will take into the way 8 in the leaf 1 and thereby prevent the tension of the spring '13 from elevating the shutter so that said shutter would not enter into the frame. This construction obviates the necessity of providing an extra lock upon the side of the building in order to retain the shutter in its open position and it will be readily seen that the locking mechanism can be added to the hinge at a very small addi-- tional cost.

What I claim is 1. A hinge comprising a pair of leaves, oval heads secured to said leaves each head being substantially one-half the length of its respective leaf, a pivot pin integral with the upper head and at one side of the center thereof and adapted to enter a socket in the lower head, a locking pin disposed through a bore in the upper head and adapted to ex- IIO posed around the reduced end of said pin 1 and in said bore whereby the pin will be directed into a bore in the lower head when the hinge is open and means to hold said pin in its elevated position when the hinge is being opened or closed,

2. A hinge of the class described comprising a pair of leaves, an oblong head on each of said leaves, one head being on the upper half of one of said leaves, and the other head on the lower half of the opposite leaf and adapted to register one above the other, a pivot pin integral with the upper head and at one side of the center thereof adapted to en ter a socket in the lower head, a locking pin disposed in a bore in the upper head and at the opposite side of the center from the pivot pin, said locking pin being longer than the head and having a reduced upper end, a spring disposed around the reduced end of the locking pin and in the bore, adapted to direct said pin into a bore in the opposite head when the hinge is opened, a handle secured to the upper end of the locking pin and a ledge at the upper edge of the lower head adapted to hold the locking pin in its elevated position when the hinge is being opened or closed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHRISTOPHER FIELDING.
